In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address.
MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.
Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.

What does the term dynamic indicate in the output that is?

How devices get their MAC or IP address.?
A device or computer gets their MAC address from their Network Interface Card (or NIC). This is not something that a user is able to change (See discussion as to why you can change your MAC address). However an IP address can be statically assigned to you which means a network administrator has physically typed out what your IP address and subnet mask is. Another way to get an IP address is through Dynamic Host Configuration Protocol, or DHCP as it is most commonly known as.
What is dynamic address mean?
Dynamic address is a term related to computer networking. It is when the IP address of system is not static.
What is the Mac broadcast address?
Ff:ff:ff:ff:ff:ff
What would be the result if the MAC address table was flushed of dynamic entries?
The switch would broadcast frames out each port except the originating port until the switch learned all the MAC addresses connected to the switch.
How can you got the Mac Address?
Any network card has its own MAC address, so it doesn't require an extraordinary effort to have your own MAC address.

What is an Active Directory Mac address?
The MAC address is the LAN/Ethernet card address there is no specfic Mac address for active directoy. Each server/PC in the world has its own unique mac address.
IP address Mac address?
A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Everything attached to any computer network has a permanent MAC address that moves with the hardware no matter where it is connected.IP address is the current interface address for your local system to the larger public internet. The IP address can be STATIC (permanently assigned) or DYNAMIC (changes every time you connect to the internet).The alphabetic names are for humans. They are translated to the xxx.xxx.xxx.xxx format for the computers to use. When you type in the name of a website the name is looked up by your browser.The MAC address is for hardware. The IP address is for communication on the internet.
Is it possible to reset a dsl modem so you get a new ip address without turning it off?
Even though modems usually get ip addresses from a DHCP server (dynamic ip address) providers usually bind the modem mac address with a dynamic address. It means that basically you have a fixed ip address. Reseting modems might not necessary mean the modem gets a new ip address. But it happens with certain services.
How to spoof MAC address on mac pro?
